In implementation of Resolution 18 adopted by the IMU General Assembly in 2010, the IMU and the ICIAM have created a joint working group to study the issue. The working group which was composed of N. Joshi, D. N. Arnold, C. Hutchins, J. D. S. Jones, M. MacCallum, P. Michor, S. Mueller, and T. Tang has finished its work and come up with a report that can be found on IMU's Web page at the following URL: http://www.mathunion.org/publications/reports-recommendations.
The working group examined the issue of why a rating of mathematical journals is desirable and submitted a detailed
proposal for IMU/ICIAM journal rating. Before going ahead and taking any further action the IMU and ICIAM want to
explore opinions on a larger scale and get as much input as possible from the mathematical community. That is why
a "Blog on Mathematical Journals" (URL: http://www.mathunion.org/journals) has been installed. The blog is moderated by a group of 6 persons (D. Arnold, C. Hutchins, N. Joshi, P. Olver (chair), F. Planchon, T. Tang).
Everyone interested can submit his/her opinion through posting an article (e-mail to: email@example.com)
and/or forwarding a comment (add a comment to a posted article by typing in the "comments" window or sending
e-mail to firstname.lastname@example.org).
Please go to the mathematical journals blog and join the discussion of the issue.
